Battery Pack Inspection – Item 3
CAUTION:
THE BATTERY PACK CONTAINS ELECTROSTATIC DISCHARGE SENSITIVE (ESD)
COMPONENTS AND, AS SUCH, IT MUST BE HANDLED WITH CARE. IF POSSIBLE,
WEAR A GROUNDED WRIST STRAP WHEN HANDLING THE BATTERY PACK
DURING INSPECTION AND MAINTENANCE ACTIVITIES. TAKE PARTICULAR CARE
TO AVOID TOUCHING THE EXPOSED CIRCUIT BOARD AND CONNECTOR PINS ON
THE BOARD.
CAUTION:
DO NOT USE ANY FOREIGN CLEANER ON ELT COMPONENTS. SUCH CHEMICAL
AGENTS CAN BE HIGHLY DESTRUCTIVE TO THE MOUNTING HARDWARE AND ELT
HOUSING, CAUSING CRACKING, FRACTURING AND OTHER DAMAGE.
1)
Check battery cells, components, and connectors for corrosion and other damage. There should be no
corrosion of the battery cells. The presence of any corrosion is cause to reject the battery pack.
2)
Check wiring for breaks, damaged insulation, and improper or damaged connections.
3)
Check housing for cracks and other visual damage.
4)
Check the battery pack expiration date.
5)
Replace the battery pack if any of the following conditions are true:
a)
After use in an emergency
b)
After an inadvertent activation of unknown duration
c)
When the total of all known transmissions exceeds one hour
d)
On or before battery replacement (expiration) date

G-Switch Functional Check – Item 4
1)
Reinstall the battery in accordance with Figure 28 on page 55.
2)
Perform this functional check within the first 5 minutes after the hour (UTC), as required by AC 43.13-1,
Chapter 12, § 12-22, Note 3.
3)
Notify any nearby control tower of your intentions.
4)
Install the 500-0079 G-switch Loop Test Connector Fixture on the ELT receptacle or jumper ELT receptacle
pins 5 and 12.
5)
Verify the ELT switch is in the “ARM” position.
6)
Monitor 121.5 MHz on an AM receiver.
7)
Activate the ELT by using a rapid forward (i.e., throwing) motion in the direction of the arrow on the ELT label,
followed by a rapid reversing action.
8)
Verify activation by listening for the aural sweep tone on the receiver. The LED on the ELT housing will also
begin to flash, indicating activation. For proof, the AM radio will verify that the RF output is operational.
9)
Reset the ELT by toggling the control switch to the “ON” position and then back to the “ARM” position.
NOTE:
After removing the G-Switch loop plug,
wait at least 60+ seconds
before a Self-Test is
done in order to get the 6 flash error, indicating the loop has been removed.
